CASTING APPARATUS.

As shown, the In the use of this invention the two sections member F is pivoted to the top or cover B or parts of the mold G are detachably onby a horizontal pivot F and is provided with gaged, respectively, with the supporting and a port or orifice f for registering with the clampingmembersFJ The supportingmem- 45 exit-port or nozzle E and with means, as a ber F is swung on its pivot F for presenting handle f, for rocking the member F on its the port to the exit-port or nozzle E to perpivot F relatively to the exit-port E and mit the entrance to the mold of the material to be cast, and during the entrance of said material the clamping member J firmly presses the mold as a whole toward the contiguous face of the supporting member F and the exitport or nozzle E, and the pivot Z locks the clamping member J in its operative position. After the formation of the cast article in the mold the supporting member F is rocked on its pivot to withdraw the port f from the exit-port or nozzle E, and during the movement of the supporting member the part K causes the lever K to be automatically rocked on the pivotal arm K, since the part K is moved substantially vertically, thus moving the clamping member J from the supporting member F and separating the sections of the mold to facilitate the removal of the cast article. These several operations can obviously be completed with minimum efiort and maximum rapidity.

The construction and operation of my casting apparatus will now be readily understood upon reference to the foregoing description and the accompanying drawings, and it will be obvious that more or less change may be made in the construction and arrangement of the parts thereof without departing from the spirit of my invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a casting apparatus, a source of supply for the material to be cast, an exit-port for communicating with the source of supply, a mold having an ingate for communicating with the exit-port, a supporting member for the mold movable relatively to the exit-port, means for forcing the material from the exitport through the ingate into the mold,aclamping member movable toward and from the supporting member, and movable means connected to the clamping member for actuating the same automatically, substantially as and for the purpose described.

2. In a casting apparatus, asource of supply for the material to be cast, an exit-port for communicating with the source of supply, a mold having an ingate for communicating with the eXitport, a supporting member for the mold movable relatively to the exit-port, means for forcing the material from the exitport through the ingate into the mold, a

clamping member movable toward and from the supporting member, a part fixed relatively to the exit-port, and movable means connected to the clamping member and said part for automatically actuating the clamping member when the supporting member is operated, substantially as and for the purpose described.

3. In acasting apparatus, a source of supply for the material to be cast, an exit-port for communicating with the source of supply, a mold having an ingate for communicating with the exit-port, a supporting member for the mold movable relatively to the exit-port, means for forcing the material from the exitport through the ingate into the mold, a clamping member movable toward and from the supporting member, a lever connected to the supporting and clamping members, and means connected to the lever for causing the same to be actuated automatically when the supporting member is operated, substantially as and for the purpose set forth.

4. Ina casting apparatus, asource of supply for the material to be cast, an exit-port for communicating with the source of supply, a mold having an ingate for communicating with the exit-port, a supporting member for the mold movable relatively to the exitport,means for forcing the material from the exit-port through the ingate into the mold, a clamping member movable toward and from the supporting member. a lever connected to the supporting member, means connecting the lever to the clamping member, and a part fixed relatively to the exit-port and connected to the lever for causing the same to be actuated automatically when the supporting member is operated, substantially as and for the purpose described.

5. Inacasting apparatus, asource of supply for the material to be cast, an exit-port for communicating with the source of supply, a mold having an ingate for communicating with the exit-port, a supporting member for the mold movable relatively to the exit-port, a standard fixed relatively to the movable supporting member, means for forcing the material from the exit-port through the ingate into the mold, a clamping member having one end provided with a guide movable along the standard and its other end out of direct engagement with the standard and connected to the mold, an arm projecting laterally from the standard, and movable means between the clamping member and said arm for moving the clamping member, substantially as and for the purpose set forth.

In testimony whereof I have hereunto signed my name, in thepresence of two attesting witnesses, at New York, in the county of New York, in the State of New York, this ith day of December, 1902,
